I have favored cleave as well, since I spam it every cycle in multiple mob situations.
The 3.0.8 cleave glyph adds an extra target to cleave, instead of the 5 rage discount. That should be pretty nice.
The devastate glyph doesn't appeal now that devastate is such an unimportant part of my rotation. And the heroic strike glyph is useless if you don't have enough rage to HS in the first place and useless if you have infinite rage.
